To aZZ whom it may concern:

" t 1 tltlJ B J De 1 anovn 1a OHN IRNIE, of the town of Birnie, 1n the Province of Manitoba, Canada, have invented certa n a" new and useful Improvements in Shocking Machines, of which the following is the specification.

The invention relates to improvements in shocking machines and the general object in of the invention is to provide a machine attached to and carried by the customary harvester or binding machine and designed to receive the sheaves discharged from the binder, form them into shock and deposit the formed shock on the ground in astand: ing position and firmly planted.

A further object of the invention is to construct the shocking machine so that it is entirely automatic in its operation and does not depend, in any way, upon the driver of the binder and further such that it is self driving, that is to say, does not depend on any of the binder driving mechanism for driving purposes. i A still further object is to provide a forward dumping shock basket designed after it has been dumped to remain witn the shock for a predetermined interval, thereby steadying the deposited shock.

A still further object of the invention is to provide an automatically operated means for initially'delivering the sheaves from the deck to the basket and afterwards for stopping delivery of the ejected sheaves during the interval that the basket is dumping and returning.

- A further object of the invention is to provide'packers associated with'the basket for pushing the sheaves into the basket, these being timed withthe binder discharge arms and being associated with a trip arm carried by the basket and designed upon the basket being properly filled with sheaves to automatically set the basketinoperation to dump the shock.

' A stih'furthe'r object is to provide a timing device arranged to cause-the basket to return to the initial sheaf receiving position after dumping thecontained shock.

With the above more important other minor objects in View, which will become more apparent as the description proceeds, the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described and later pointed out in the appended claims, reference being had to the accompanying drawings in which:

Fig. 1 represents a front View of the shocker attached to the binder and in the sheaf receiving position.

In thedrawings like characters of reference indicate corresponding parts in the several figures.

1 represents the main frame of a binding machine or harvester, 2 the master or bull wheel thereof and' 'the deck, the deck carrying the customary 'discharge arms 4 mounted on the discharge arm shaft 5.

The above parts are of'ordinary construc- 100 tion and they are well understood are not herein further described.

To the binder frame I secure permanently, such as by bolting, a pair of side brackets 6 and 7 which support inthe horizontal position a substantially rectangular main shocker frame 8. Forwardly to this frameI secure permanently a bearing plate 9 whichis fitted with front and rear bearings 9' and 9 (see Fig. 5), in the rear or inner one of which I mount a countershaft 10 which supports pivotally a pair of rearwardly extending equal length side arms 11 and 11*, the rear ends of which carry a driving shaft 12 to which I secure a driving wheel 13 and a chain wheel 13'.

14 represents a bridge or arch extending across the shocker frame in a location slightly in advance of the shaft 12 and 15 and 15 are two upstanding guide rods attached to the side members 11 and 11 and having their upper ends passing slidably through the arch 14:. Cushion springs 15 and 15 are mounted on these rods between the side arms and the arch, these serving to continuously press the wheel 13 down to- Wards the ground so that it will always ride the ground regardless of the variation in the elevation of the shocker frame. The inner end of the counter-shaft is fitted with a clutch indicated generally by the reference character A and comprising what might be termed a loose member 16 and a fixed member 17, the fiexed member being permanently secured to the shaft whilst the loose member is freely mounted thereon and is formed integral with a chain .wheel 16 connected by a chain 16 to the chain wheel 13'.

The clutch is best shown in Figures 10, 11 and 12, the fixed member appearing in side elevation and plan View in Figures 10 and 11 and the loose member in side elevation in Figure 12. This clutch is of common construction, the fixed member presenting a rim 17 provided with a pair of outstanding diametrically opposing fins 17 x and 17 and a pair of diametrically opposing slots 18 and 18 and fitted interiorly with a pair of pivoted T-shaped rocker arms 19 and 19 connected by a link 19 and having one of the arms connected by a spring 20 to the hub of the clutch member and the other of the arms fitted with a roller 20' located outside of the rim.

The loose member 16 is rotatably mounted on thecountershaftand is fitted with a rim provided on the interior side with a plural ity of seats or notches 21 designed to receive the roller. Associated with the clutch is a trip lever 22 having a striking end 22 and the inner end supplied with a roller 22 designed to enter the slots 18 and 18 and also to ride the fins.

By observing Fig. 10 and considering the loose clutch member in position such-that it contains the roller 20 it will be apparent that when the trip lever is in the position shown in full outline the roller 22 serves to hold the upper rocker arm back (this against the action of the spring 20) and thereby holding the roller 20 clear of the seats 21. Consequently the loose clutch member can rotate freely and is driven by the chain wheel 13. However should the free end of the trip lever be struck downwardly against the action of the pressure spring 22 the rocker arm 19 will immediately swing to the dotted position and the roller 20 Will engage one or other of the notches 21 and thereby cause the clutch member 17 to turn with that 16 and accordingly impart rotary movement to the countershaft from the rear axle'12.

The countershaft will be driven for half a revolution, this being explained by the fact that immediately the lever 22 is tripped the clutch member 17 starts to rotate and the roller 22 dropping back on to the fin 17 rides this fin and the face of the rim until the slot 18 is presented when it strikes the rocker bar 19 withdraws the roller 20 and passes into the slot 18, thereby locking the roller 20 in its released position and stops in the half revolution, the furtherdriving of tne countershaft.

I have not entered into a minute descrip tion of this clutch as I have already stated it is now in use and it is believed that a general description of its construction and working will be sufficient for the purpose of this description. Here I might also state that in so far as my machine is concerned any clutch which can be tripped and will reset in half a revolution for further tripping will accomplish my object in so far as the clutch is concerned.

23 represents the main basket supporting arm, this arm being pivotally attached to the front end of the shocker frame and extending upwardly and outwardly and suspending the basket B in an elevated position above and to the side of the shocker frame. The basket arm has the lower end in the form of a pivot shaft 24 which is rotatably mounted in thebearing 9. From this shaft the arm extends vertically upwardly as indicated at 23, then horizontally outwardly as indicated at 23 then horizontally rearwardly as shown at 23 and finally downwardly in a vertical direction as inclicated at 23 where it is permanently secured at 25 to the top of the basket B and in a central location.

From this description it will be seen that this arm is of a double L-shape, both the L-shaped parts being contained in vertical planes and with the one extending in a direction at right angles to the binder and the other going rearwardly and parallel with the binder. The outer ends or the shaft24 and the countershaft lU 'are fitted with cranks 26 and 26 connected 'byj a'link 26? and the crank 26' is considerably" longerthan crank 26' so that a completerotation of the which 'it'" controls froman upright position as shown'in Fig. 3 to a horizontal position as shown in dotted out-line inFig. 3, which latter position isthedumpedposition of the basket. f

Here I wish it to be noted that owing to the formation of the clutch both the countershaft and the shaft 24 are automatically locked against movement when the basket arm 23 is in the upright and in the horizontal positions and provision has to be made as later described for unlocking the arm 23 to permit the basket to pass to dumping position and also to allow it to return to the initial sheaf receiving position after dumping. i r i The basket is of an open ended cone shape and presents a side filling opening C and is mounted with the large or butt end to the front. It is formed from two suitably'reinforced metallic sections 27 and 27 connected together by suitable side hinges 27* at the side remote from the binder;

7 From this itwill be seen'that the'top half is stationary, being connected directly at 25 to the arm 23, whilst the bottom half is free to swing, turning at the hinges. The hinged or underside of the'jbasket-is controlled by a bowed controlling lever 29 pivotally secured at 29 to the top of the basket section27 and having the lower end connected by a pin 29 to the lower section 27' of the basket in a location below the hinge. The latter end of the leveris slotted asshown at '30 to receive the pinand in a locationdirectly above the pivot point 29 the lever is supplied with an outstanding arm 30 which is connected by a comparatively strong'tens'ion spring 31 to the basket arm 23, the spring having a natural tendency to swing the lower end of the armout and'open'the lower half of the basket (see Fig. 6). This tend; eney of the spring however iscontrolled by a "locking roller 32 normally engaged in a receiving notch '32 provided in theupp'er end of the lever, the roller being; carried, by an arm 32 pivotally mounted on the basket as indicated at'32 and having the end remote from the roller connected to the basket by acmpressioni spring 33 designed to'forc'e the roller normally from the notch. The arm -32- is provided with an inclined portion 32 located between the pivot -point 32 and the spring eeandthe inclined-part of the leveris straddled by a standard 34 fitted with a. roller 35 riding the basket and designed in the locked position as shown in Fig. 6 to counteract the action of the spring 33 and consequently retain the roller 32 in the locked position within the notch 32* with the parts so set that no movement can occur'in the arm 29 with the result that the under half of the basket remains in the closed position. It will be observed however that should the standard be moved towards the spring 33 the spring will be allowed to expand, this owing to the inclined part 32?, and consequently the roller 32 will be freed from the notch and thereby allow the spring 31to actuate the lever 29 and open the under half of the basket. The parts associated with and controlling the movement of the standard are now described':

36 represents a bracket extending from the standard towards the arm 29 and providing a bearing for a swinging shaft 37 pivoted at 37 to' the top of the basket and having the rear end fitted with a roller 37* riding the adjoining face of the lever 29; The other end of the shaft 37 is connectedby a pivot pin 38 to a cross rod 39, the outer end of which is slidably carried by the inner bracket of a pair of brackets 4:0 and 41 mounted on the top of the basket and the inner end of which is connected to one end of a substantially U-shaped lever 42 pivotally secured to the basket arm 23. To the other end of the latter lover I attach a'link 43 which isconnected pivotally to a further horizontally disposed lever 44: pivotally attached tothe basket arm and having the free end thereof connected toan operating bar 45 pivotally anchored at 4:6 to the shocker frame in a location to the rear of the shaft 243 (see Fig. 5). a

The above arrangement provides for the releasing of the swinging part 27 as the basket passes the dumping position as it will bar 45 which will act through the various connections to force back the standard 34k and consequently allow the spring 33 to extend andrelease the roller 32 from the lever 29,'the' said lever then operating under the aotionof the spring31 to open the swingi'ng half of the basket.

Here I might explain also that in the turning action of the basket from dumping to sheaf receiving position this movement is reversed and the upper end of the lever 29 is crowdedback by the roller 37 until the section 27 of the basket has been closed and locked y the roller '32 ire-entering the notch 32*. vi

The tripping of the basket is eiiected automatically coincident with the filling thereof with sheaves and the tripping mechanism embodies the parts. now disclosed.

47 represents a trip rod connected by a V hinge 47* to the basket and having a knee 47' extending normally through theslot 48 provided in the basket. The upper end of this rod is attached pivotally to a crank 49 located at the rear end of a short shaft 49 carried by the basket arm and the forward end of the crank is fitted with a crank 49* connected by a link 50 with a crank 51' located at the end of a further rod 51 positioned at right angles to the shaft 49 and carried by the member 23* of the basket arm. The innermost end of the latter rod is fitted with a kicker 52 which normally engagesthe upper end of a vertically disposed operating rod 53 carried by the vertical portion 23 of the basket arm. The lower end of the rod 53 rides the free end of the trip lever and a coiled spring 54 holds the said rod normally up, the spring engaging the collar 55 fastened to the rod. 7

From this construction it will be seen that as the'basket becomes filled with sheaves the knee 47 will be pressed out and this movement will effect through the various connections a down swinging of the kicker 52, ,a down movement of the rod 53 and the consequent release of the clutch lever which will immediately cause, through the engagement of the clutch members, a rotation in the countershaft and the forward swinging of the basket arm, which latter movement turns the basket into shock dumping position.

As soon as the basket reaches the dump- IF ing position the swinging section 27 thereof opens in the manner herein before disclosed to release the shock and coincident with the freeing of the shock the knee is free to regain its normal position, thereby releasin the clutch lever and disconnecting the clutch members, with the result that the basket stays in the dumped position until the clutch members are again engaged by a timing mechanism now described.

The brackets 10 and 4:1 herein before mentioned provide a bearing for a shaft 56 on which I have mounted a timing wheel 57 and a gear wheel 58, the gear wheel-meshing with a further gear wheel 59 located on a cross shaft 60 also carried by the brackets. The inner end of the cross shaft is mounted in a bearing 61 secured to the basket arm and the end of the shaft adjoining the said hearing is fitted with a striker 62 which is designed in the turning of the shaft to engage a vertically disposed slidably mounted resetting rod 63 carried by the basket arm and normally held up by a spring 64 similar to that 54.

In the forward dumping of the basket the wheel 57 will engage the ground (see dotted outline Fig. 8) and will accordingly be turned, with the result that the striker 62 will come around, hit and. pass the upper end of the rod 63, which at this time is more or less in the horizontal position as shown in dotted outline in Fig. 3. The end movement so produced in the rod 63 is utilized to trip the clutch as it will be observed in Fig.3 that in the dumped position of the basket the said trip rod in moving backwardly will strike the free end of the trip lever and consequently disengage the clutches. V

This timing appliance accordingly provides for the basket remaining in the dumped position a short time to steady the sh ock as the wheel 57 has to turn one revolution beforejthe striker 62strikes. Immediately however the striker strikes the rod 63 the clutch lever is thrown in a direction which will engage the clutches and cause the counter-shaft to rotate and return the basket arm to its original upright position, this movement being transmitted through the link 26*.

When the. basket arm has reached the upright position,,and this in half a revolution of the clutch, the trip lever roller -22 drops into one of the slots and simultaneous- 1y releases the roller 20 from the clutch member 16, with the result that further turning of the countershaft is stopped and the basket armbecomes locked in theup-.

right position with the basket set ready to receive the sheaves.

The time which the basket remains in the dumping position can be gauged by varying the ratio of the gears 58 and 59 as will readily be understood.

The open space between the basket and the deck is spanned by combination delivery and retarding prongs 65, the outer ends of which pass into the basket through the opening C and the inner ends of which are secured to a carrying shaft 66 supported on suitable bearings carried by stationary standards 67 and 68 extending upwardly from the brackets 6 and 7. A crank 69 is secured to the forward end of the latter shaft and is connected by a link 70 to a second crank 71 extending from a lower shaft 71 carried by a bearing 72 permanently secured to the lower end of the standard 67.

73 represents a further crank permanently attached to the shaft 71 and connected to a pair of pivotally connected breakjoint links 74 and 75, the link 75 being attached to a stationary arm 76 extending from the bearing 72. 77 represents a pulling arm permanently connected to the upright portion 23' of the basket arm and having the free end pivotally fastened at 78 to the links. 1

In the normal position of the basket the prongs 65 are positioned as shown best in Fig. 1 and are designed to deliver the sheaves from the deck to the basket. However, during the interval that the basket is being dumped I desireto stop the oncoming sheaves and to this end the mechanism associated with the prongs has been provided, such being operated by the forward swinging of the basket arm and effecting through the pulling arm 77 the breaking of the joint between the links and the consequent swinging of the crank 73 in a direction which will shift the link '70 upwardly and accordingly raise the prongs clear of the basket and to a position such that they will hold any sheaves that may be discharged from the deck when the basket is being dumped. Y

Obviously the back swinging of the basket supporting arm reverses the movement just described and causes the prongs to go back to their normal delivering position when the basket has returned to its sheaf receiving position.

7 I To the upper side of thebasket in a location above the opening C I provide a plurality of packers 79 all extending from a common supporting shaft 80 previously mounted on the basket. The packers are held normally in their up position. by a spring 81 attached to the basket and to a crank like arm 82 extending from the shaft. 83 represents a fixed arm extending towards the binder from one of the shaft bearings and carrying pivotally a lever 84, the outer end of which is connected by a link 85 to the crank arm 82 and the freeend of which, or that next the binder, is designed to be engaged by a roller 86 locatedat the end of a crank 87 secured to the discharge arm shaft 5.

Here I might explain that on the pres ent hinders the discharge arm shaft is rotated by the binder mechanism and is designed to discharge a sheaf from the deck each rotation of the shaft. Accordingly each time the discharge arm shaft rotates the roller 86 is engaged with the free end of the lever and this immediately after the discharge of the sheaf from the deck, which action causes the other end of the lever 84 to pull down on the crank 82 and consequently swing the packers inwardly towards the basket and press the passing sheaf into the basket.

In theactual operation of the shocker the sheaves delivered to the basket are formed by the basket into a shock and aboutthe time the basket is becoming filled there will .be a pressure exerted by the packers and through the sheaves to the knee 47 and this pressure will effect the out pushing of the knee and the consequent tripping of the clutch to 'set the basket arm in motion as i already described. The instant the basket arm starts it exerts two pulls, one through the arm 77 to raise the prongs and retard the. sheaves and another through the .bare5 to release the swinging part 27 of swung back to the initial position by the throwing in of the clutch which is brought about by the trip rod 63. The instant the basket arm takes its original upright position the clutch goes out of commission and the movement stops with all parts reset and ready for further delivery of sheaves.

The front or large end of the basket carries a plurality of vertically disposed fingers 88 which cross the basket and are permanently secured to the stationary section thereof. These fingers preventthe formed shock from sliding bodily out ofthe basket when it is being dumped. In the dumped position of the basket they simply withdraw in the onward movement of the machine from beneath the planted shock.
